Because the nodes are not databases, they are Apache/PHP web servers
which have file system caching where the URL = directory/file. The XSLT
also converts XML objects to PHP code. So basically a content editor can
do something like:
<br /><br />
This is my course description: <coursedesc courseid="AAA 123" />
...
etc.
and the XSLT converts the <coursedesc /> tag into a PHP function (that
does a db lookup).
Cheers,
Chris
